Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018864, here are decompositions:

5 + 1018859 = 1018864
47 + 1018817 = 1018864
53 + 1018811 = 1018864
101 + 1018763 = 1018864
131 + 1018733 = 1018864
167 + 1018697 = 1018864
191 + 1018673 = 1018864
251 + 1018613 = 1018864

Showing the first eight; more decompositions exist.
